This is a weird one, and super duper annoying.
On a side project, I upgraded from the Asset Store version to the beta. Now each time I start the game in the editor, it immediately pauses.
It is as if Error Pause is triggering, but there are no errors.
I have searched all files in the entire project (all code, including packages and my own) for Debug.Break, Debug.DebugBreak, and isPaused = true, and although a few exist in the pathfinding project, they’re all commented out.
I can prove that it is indeed the pathfinding project, because if I disable the pathfinder in the project, the weird pausing behavior no longer occurs.
